There may be a sticker on the new unit with a Wifi SSID and password on it, which you will have to enter on your WiFi devices.
If there is no sticker, did you set it up ourself, or did a Comcast tech do it for you?

Are you WiFi devices seeing your WiFi network? Is the SSID of your router appearing in your available networks list?

I would hit the reset button on the back of the modem which will factory rest the modem. Here is a link to do step by step set up. If you are still having issues please repost any error you are getting. Also the model of the modem/router from comcast. If this did help you resolve please mark as solution as this is great appreciated.

I have seen an authentication error and this is how i fixed it. This may or may not be your problem depending on the type of network, but its worth a shot.
What you want to do is open the properties of the wireless network. In windows XP this can be done by right clicking the wireless icon, going to View Available wireless networks, then on the left hit "Change Advanced settings.
Go to the Wireless Networks Tab, Select your network near the bottom, then hit properties.
In the new window, go to the authentication tab and make sure the first box is Unchecked.
This solved the error msg "Windows could not authenticate you on this network" or something along those lines.
Hope this helps
